Stocks rise modestly in midday trading

NEW YORK — Stocks rose modestly in midday trading on Wall Street today after several big companies turned in solid earnings.

The Dow Jones industrial average was up 32 points, or 0.2 percent, to 15,554 as of noon.

The Standard & Poor’s 500 index was up five points, or 0.3 percent, to 1,690. Seven of the index’s 10 industry sectors rose, led by technology stocks.

The technology-heavy Nasdaq composite rose 28 points, or 0.8 percent, to 3,627. Apple, the biggest component of the index, rose $8.49, or 2 percent, to $456.

Goodyear Tire & Rubber jumped $1.70, or 10 percent, to $18.74, the biggest gain in the S&P 500 index, after reporting that its second-quarter earnings more than doubled. Sales in Latin America rose sharply. Pfizer and Masco also rose after reporting earnings that were better than investors were expecting.

Jim Dunigan, chief investment officer of PNC Wealth Management, said investors have been encouraged by a recent pickup in mergers and acquisitions, including Monday’s blockbuster deal combining Publicis Groupe and Omnicom Group to create the world’s largest advertising firm.

The resurgence in corporate deals “gives investors confidence to make purchases at these levels,” Mr. Dunigan said. “When you see others buying, it gives people a sense that they’re not making a mistake.”

Traders were also keeping a close eye on the Federal Reserve. The central bank began a two-day policy meeting today.

The Federal Reserve has been buying $85 billion in bonds every month to keep interest rates low and encourage borrowing and hiring. The Fed has said it might start to pull back on the stimulus later this year if the economy continues to improve, but the timing remains uncertain.

Among other stocks making big moves:

— Pfizer rose 42 cents, or 1.5 percent, to $29.97 after the pharmaceutical company reported that its income more than quadrupled, helped by the sale of its animal health business.

— Masco jumped $1.33, or 6.7 percent. The home furnishings company posted earnings that beat the forecasts of financial analysts as the company benefited from a surge in home construction.

— Time Warner Cable fell 94 cents, or 0.8 percent, to $114.26. The giant cable company is enmeshed in a nasty fee dispute with CBS over programming fees and is threatening to pull the broadcaster off its systems.

— Coach slumped $5.26, or 9 percent, to $52.59 after the upscale handbag maker reported a 12 percent drop in fourth-quarter profit as its home market of North America remained weak. Coach also said two more executives were leaving the company.
